Function and operation explanation
1. 16-bit operation (INT, INTP)
The binary floating decimal point of the device specified by is converted into BIN integer, and is
transferred to the device specified by .
Instruction of reverse converting operation
Reverse converting operation of the operation of this instruction is FLT.
→ As for FLT instruction, refer to 11.10.
2. 32-bit operation (DINT, DINTP)
The binary floating decimal point of the device specified by is converted into BIN integer, and is
transferred to the device specified by .
Instruction of reverse converting operation
Reverse converting operation of the operation of this instruction is DFLT(FNC49) instruction.
→ As for FLT instruction, refer to 11.10.
